NON-SLIP BATH MAT: The high-end bath and shower mats have 200 special large suction cups. The different suction cups absorb stronger than the other small suction cups, which help to stay in place on smooth and clean surfaces. DRAIN HOLES DESIGN: Our mat has small drainage holes to allow water circulation. Without holes, water can collect on the carpet, making it slippery and accelerating mold growth. Our bath mat is antibacterial and mildew resistant. LARGER SIZE: Our extra large and generously sized bath mat measures 40 * 100cm (15.7 * 39.4in) and provides excellent coverage. The tub mat has a textured surface for comfortable safety. Relax with the comfort of the small bubbles raised by gently massaging your tired feet. SAFE AND ECO-FRIENDLY: Our antibacterial bath and shower mats are made from high quality, allergen free vinyl. BPA-free, non-toxic, phthalate-free, latex-free, no toxic odor. MACHINE WASHABLE: Our durable mat is machine washable for easy, hassle-free maintenance and keeps it looking fresh.
